We present an identification key to the scorpion species of Yunnan (China) with notes on the distribution and ecology. Euscorpiops kubani is recorded for the first time for China. The redescriptions of Euscorpiops shidian and Euscorpiops kubani are provided. The number of known scorpion species from Yunnan is raised to nine.

An updated checklist of the scorpion fauna of Iran, as well as a brief history of taxonomic research on scorpions of Iran is presented. The checklist is based on records of scorpion species whose presence has been confirmed in Iran through field expeditions, examination of scorpion collections, literature review, and personal communications from researchers. The scorpion fauna consists of 51 sp...

This paper records for the first time the exocrine pancreatic response to scorpion venom, in this case that of Tityus trinitatis, a scorpion endemic in Trinidad. The crude venom injected intravenously into fasting anaesthetised dogs induced a secretion of the exocrine pancreas. The secretion evoked was rich in enzymes.

background : in this study, we investigated the lethal potency, electrophoretic protein pattern and in vivo effects of hottentotta saulcyi scorpion venom in mice. methods : scorpions were collected at night, by using a uv lamp from mardin province, turkey. venom was obtained from mature h. saulcyi scorpions by electrical stimulation of the telson. the lethality of the venom was determined by i....

Scorpion venoms have been studied for decades, leading to the identification of hundreds of different toxins with medical and pharmacological implications. However, little emphasis has been given to the description of these arthropods from cellular and evolutionary perspectives. In this report, we describe a transcriptomic analysis of the Mexican scorpion Centruroides noxius Hoffmann, performed...

The episodic nature of natural selection and the accumulation of extreme sequence divergence in venom-encoding genes over long periods of evolutionary time can obscure the signature of positive Darwinian selection. Recognition of the true biocomplexity is further hampered by the limited taxon selection, with easy to obtain or medically important species typically being the subject of intense ve...

Death due to scorpion envenoming syndrome is a common event in many of the tropical and nontropical counties. Initial transient hypertension is commonly observed in scorpion sting victims. Scorpion envenoming causes autonomic storm resulting in initial transient hypertension followed by hypotension, cold clammy skin, hypothermia, cardiovascular disturbances, acute myocarditis, sarcolemmal defec...

Scorpions are generalist predators, capturing a great variety of arthropods including even small vertebrates (Polis, 1990), however, they are also subject to predation, especially by vertebrates such as amphibians, reptiles, birds and mammals (Polis et al., 1981; McCormick and Polis, 1990). Regarding the invertebrates, there are reports of predation by coleopterans, chilopods, solpugids, others...
